'Theinvention Will be 'best'understiodvby Figure V1 is' a partial. elevation, aiid vpartial :vertical section ofv asilo built in acrnan'nei in which the roof portion is connested With-the wal-ls, Fig. 3 ,is abfragmental vertical seotionshovving a modified form of do'or1supporting means, Fig. i is a fragjmental/section-taken on line in Fig. '3, i

Fig. 5 isa horizontal section taken on line J 5-5 'in Fig. 1, Fig. 6 is a view in perspec-v tive illustrating the method of securing'the ladder rungs to :.-a metallic reinforcement,` and Fi 47 is a view in perspectlve showin' the Q construction f the door opening an doors mounted therein.

The preferred form of Reonstruction as illustrated in the drawings comprises an outer Wall 8 and an inner vvall 9 spaced apart forming an air space l() therebetween, and-tied together by 'means of rods 12 hav? ing their ends embedded in such inner wall and' outer Wall. The inner Wall [9; is' pron vided lvvith a metallic reinforcement, preferably of Wire netting 1l; and such metallic reinforcement is continued through the easing or chute 13 which incloses the door openinglll.' The bottom of the chute 13 is enlargedl forming a vestibule 15 Winch-1s provided with a door opening and door 15 hingedly secured therein and `provided as a means for the entranceandl removalot iaterial trom the silo.

the supporting member 25 is adapted to en#v gage [to supportl such door section. The

door sections are preferably provided in 4 even numbers with the ladder rungs' 26, as clearly illustrated, so that each hooked member 25 may engage and support one Yso;

door section 20. Each hook 25 is pivot'a'lly.4 vmounted on la ladder rung 26, as clearlT illustrated in the drawings. The lowerrnostl--.

95 edge of the door so that `free access may be i.

rung 26 is preferabl for-med in only one "had through the door when said door secf and secured in the metallic lreiniorcement tions are removed.

and-door. sections 20 formed of Wood and. provided with tonguevand groove jointsQS,

as clearly illustrated in Figfl. p Such door sections may be supported by means of Wedges 29 Whichengage the outer side ,of

*such door section, and a rung 26, as clearly r shown -in Fig; 35 Iltis preferred to provid enough door sections to ll the door opening i3 except one so that the door sections may be slid upwardly leaving an open space 30 at the height of thezmaterial in the silo so that it'may be easily accessible, and as' the material is usedrom the silo.; the door sections aremoved upwardly and sopported as has been described,

l/Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of' variation and modification Withoutdeparting from `the spirit of the invention. I.; therefore,' do not wish to be limited to the precise details of/construction set forth, but

- desire' to avail vmyself of such `variations and modications as' come within the scope of the appended claim.

Having described my invention what l claim as new and desire to secure by Let ters Patent is:

A concrete structure comprising a lateral Wall provided with a door opening extending throughout the height of the Wall, a

roof, a chute communieatin and co-extenl25 sive with said opening and' avmg parallel side Walls formed vintegrally with said lat? eral wall, a reinforcement consisting of vertical and horizontal interwoven members embedded in, said side Walls and extending 30.

'stantially as described.

in testimony whereof 1 have signed my name to this specification in the presence of two subscribing Witnesses..
